I just used the #13 How-to guide from MYDELOREAN.NET, for testing the idle speed switch. I tested the switch itself, and it's fine. I also have continuity through the black/green wire from the switch to the inline diode. Also, from the "upstream" side of the diode, I get 0 ohms between that and the chassis ground with the gas pedal at rest, and about 27 ohms once I press the pedal (open the switch) However, I do not get the <few hundred ohms on the other side of the diode, which is pin 8 of the cable, per the guide. I get totally open with the gas pedal at rest (switch closed) and when pressed (between pin 8 and chassis). Is the diode bad? How can I test the diode itself? Can I get locally at an autoparts store, or do I need to order from a D vendor?
